Apparently restricted to higher peaks and sheltered gullies and slopes in the Grampians and on Wilsons Promontory (e.g. Sealers Cove), usually in rocky sites.

Once regarded as a variant of B. integrifolia but differing from that species in its thinner, smoother bark, pale yellow flowers with a greyish limb, summer flowering period, larger follicles that retain their seeds longer, and in its not strictly coastal distribution.

Possible hybrids with B. marginata have been observed in the Grampians.
